Allele frequencies are unaffected by assortative mating, but genotype frequencies .
<h3>Assortative mating: </h3>
Individuals with similar phenotypes and genotypes mate with others more frequently than is anticipated under a random mating pattern in assortative mating, which is a mating pattern and a type of sexual selection.
<h3>Frequencies of genotypes:</h3>
A population's genotype frequency is calculated by dividing the number of people having a particular genotype by the overall population size. The genotype frequency in population genetics is the frequency or ratio (i.e., 0 f 1) among genotypes inside a population.
<h3>The frequency for alleles in biology:</h3>
The term "allele frequency" describes the prevalence of an allele in a population. It is calculated by calculating the number of times the allele occurs in the population and dividing by the sum of all the gene copies.

Answer:

Explanation:
Here by ideal gas equation we can say

now we know that pressure is kept constant here
so we will have

since we know that number of moles and pressure is constant here
so we have

now we know that initial temperature is 17.8 degree C
and finally volume is doubled
So we have

so final temperature will be


Answer:
Current, I = 3.57A
Explanation:
A current of I amperes means that I Coulombs of charge flows through the conductor (heating coil) per second.
Therefore, in time t, the total charge (Q) passing through any point in which the current (C) flows will be given by the equation;
Q = It
Where; Q is the charge in coulombs; I is the current in amperes; t is the time in seconds.
From the question, we were given the following parameters;
Q = 25C, t= 7secs and I =?
From the equation, Q = It
We make current, I the subject of formula;
Thus, I = Q/t
Substituting into the equation;
I = 25/7
I = 3.57Amp.
